Summary Summary of gene provided in NCBI Entrez Gene.
The protein encoded by this gene is a connexin and is a component of lens fiber gap junctions. Defects in this gene are a cause of zonular pulverulent cataract type 3 (CZP3). [provided by RefSeq, Jan 2010]

UniProt ID Q9Y6H8
Protein name Gap junction alpha-3 protein (Connexin-46) (Cx46)
Protein function Structural component of lens fiber gap junctions (PubMed:30044662). Gap junctions are dodecameric channels that connect the cytoplasm of adjoining cells (By similarity). They are formed by the docking of two hexameric hemichannels, one from each
